The vase is made from segments cut to test the accuracy of the segment cutting jig so it is not premium material. The segment layers were glued up without any particular design in mind, but when I started turning I thought vase. The bottom is larger than the top so I decided to hollow from both ends and that led to the need to somehow close the bottom. The solution to closing the bottom some how became a 3"-8TPI threaded plug that morphed into a holder for a small Tupperware tumbler. The top edge of the tumbler is larger then the inside neck so when the plug is screwed tight it is locked in.
